==== PC133 ====
'''PC133''' is a computer memory standard defined by the [[Joint Electron Device Engineering Council|JEDEC]]. PC133 refers to [[SDR SDRAM]] operating at a clock frequency of 133&nbsp;MHz, on a 64-bit-wide bus, at a voltage of 3.3&nbsp;V. PC133 is available in 168-pin [[DIMM]] and 144-pin [[SO-DIMM]] form factors. PC133 is the fastest and final SDR SDRAM standard ever approved by the JEDEC, and delivers a bandwidth of 1.066&nbsp;GB per second ([133.33&nbsp;MHz * 64/8]=1.066&nbsp;GB/s). (1&nbsp;GB/s = one billion bytes per second) PC133 is [[backward compatible]] with PC100 and PC66.
